The $500 Build

Looking to build a powerful, expandable home office PC for under $500? No problem! This guide lists all the parts you'll need to put together a balanced computer that has the power to handle any office task. There's even an option to turn it into a serious gaming machine for under $650! And don't worry - if you need help building your system, our Builder's Guide to Assembling a Basic PC will walk you through every step, providing plenty of detailed photos and tips.

For June 2017, we go with the sub-$100 CPU king, the Intel Pentium G4600. Intel may have branded this a "Pentium," but for all intents and purposes, this is a mid-range Core i3 processor in disguise! The key is the Hyperthreading technology that Intel has added to several Pentiums in the new Kaby Lake range, with the G4600 being the fastest. This processor has two physical cores running at 3.6GHz, plus two virtual cores provided by Hyperthreading, allowing it to handle serious multi-tasking without breaking a sweat! It even has the built-in Intel 630 Graphics, just like more expensive Core i3 models. This system also features 8GB of DDR4-2400 RAM in a dual-channel configuration and a quick 250GB solid-state drive, ensuring that it will deliver an ultra-smooth computing experience unlike any you'll get from similarly-priced off-the-shelf systems. Only around 30% of pre-built desktops on the market today include SSDs, and most of the models that do are extremely expensive. New this month are the stylish and compact SilverStone PS12 case and the cost-effective EVGA 450 BT power supply, both of which offer unmatched value for the dollar.

The beauty of this system is that it can be customized in so many ways. For power users, we suggest an optional upgrade to a quad-core, which is ideal for multi-tasking, computational work, or video editing. And for gamers, we suggest an optional upgrade to the powerful GeForce GTX 1050 Ti 4GB video card, which offers amazing performance for under $150. Note that if your total budget is significantly below $500, we recommend that you buy a pre-built system. Building an ultra-low-price PC is difficult if you need a copy of Windows (about $100 on its own and included in this $500 build). Our Desktop Buyer's Guide includes several capable yet inexpensive pre-built systems, so check them out if you're on a very limited budget.

The $500 Home Office PC - June 2017


    Pentium G4600

    Released in early February, the Kaby Lake-based Pentium G4600 is the most powerful sub-$100 CPU ever released. While its model name doesn't give away what lies beneath, this is a 3.6GHz dual-core, Hyperthreaded processor, which means it's much faster than the 3.5GHz G4500 dual-core CPU released in 2015. The two virtual cores provided by Hyperthreading means it operates a whole lot more like a $120 Core i3 processor than any previous Pentium processor ever could. Plus, with its built-in HD 630 graphics chip, this processor will easily handle any home PC use, including streaming high-def video.

    The Guru's Tip:

    Some PC builders may wonder whether they should use a Core i5-7500 quad-core CPU instead of this Pentium for their home office computers. Here's the simple answer: for basic office tasks like e-mail, Internet, and word processing, the Pentium is the equal of the much more expensive quad-core. But if you're interested in high-resolution video or photo editing or serious gaming, then go with the quad. It will drop right into this build with no other modifications.


    Asus Prime B250M-A

    This inexpensive but feature-rich B250-based board is the perfect pick for this build. It has VGA, DVI, and HDMI video outputs, one PCIe x16 expansion slot, and two PCIe x1 slots, and unlike a lot of low-cost boards, four RAM slots. It also has several cutting-edge connectors, including a USB Type-C port and dual M.2 SSD slots.

    The Guru's Tip:

    Note that while some older B150-based boards may be able to support the Pentium G4600 after a firmware update, for guaranteed support, your only choice is a B250-based model.


    Crucial 2x4GB Ballistix Sport LT DDR4-2400

    The new Intel Kaby Lake platform provides a number of benefits, one of which is the ability to run faster DDR4-2400. The previous generation could only support DDR4-2133. That provides a nice speed boost in a lot of applications, particularly when using the Intel CPU's built-in video. By the way, using a pair of 4GB sticks rather than one 8GB stick allows for "dual channel" operation, boosting not only CPU performance, but more significantly, built-in video performance.

    The Guru's Tip:

    While a total of 8GB is plenty for all mainstream uses, if you'd like to work on high-res photo or video editing, go for Crucial's 2x8GB DDR4-2400 kit.

    Solid-State Drive:

    WD Blue M.2 250GB

    We now recommend that most builders choose an SSD over a hard drive, and specifically a drive using the compact M.2 form factor. The responsiveness of a system with an SSD is so superior to systems with a hard drive that we simply don't think you should build a PC in 2017 without one. And the M.2 form factor makes installation so much easier, as no cables are required - the drive slots right into the motherboard like a memory stick. Among all budget M.2 drives, the Western Digital Blue is the clear winner, with the best combination of price and performance.

    The Guru's Tip:

    Two notes on installing this drive: first, you must use the motherboard's upper M.2 slot, as the lower slot is only for PCIe drives (this is a SATA drive). Second, to affix this drive to the motherboard, you'll need a jeweler's type screwdriver.


    SilverStone PS12

    The PS12 is an updated version of the SilverStone PS08, which we reviewed and still use to this day! It has an ultra-compact footprint, meaning it will slip in just about anywhere, despite being able to hold quite a lot of powerful gear! To keep things cool and quiet, it uses a single front-mounted 120mm fan, a perfect setup for an efficient system like this one.

    The Guru's Tip:

    As the PS12 is not available in all regions, we're linking to similar SilverStone models where applicable.

    Power Supply:

    EVGA 450 BT

    EVGA's new 450W BT model offers unmatched value, providing Bronze-rated efficiency and quiet operation. And the reality is that this build will use less than half of this unit's rated power output, even with an added video card, meaning you'll have power to spare!

    The Guru's Tip:

    This unit is backed by a 3-year warranty and EVGA's excellent customer service. Note that as of our latest update, it's available only in the U.S., so we've provided substitutes for readers in our regions.

    Optical Drive:

    LG 24x DVD Burner GH24NSC0B

    While you may not use it much, when you need it, you'll be glad you have a DVD burner in your system. For starters, it makes installing an operating system and motherboard drivers so much easier. We think that justifies the cost on its own!

    The Guru's Tip:

    Because two SATA cables are included in the box with the motherboard used for this build, you don't need to buy an extra SATA cable for the optical drive or the SSD, but you will if you also add a third SATA device beyond an optical drive and a main system drive.

    Operating System:

    Microsoft Windows 10

    In April of 2017, Microsoft's Windows 10 marked its one-and-a-half year anniversary, with a huge new update called the "Creator's Update" to further distance it from the long-forgotten Windows 8.1. In addition to its superior usability, it also has lots of fine tuning under the hood to improve performance and provide greater customization options.

    The Guru's Tip:

    Note that Microsoft no longer offers free upgrades to Windows 10 from older versions of Windows, and is cutting off support for Windows 7 almost entirely on new machines.

    Hard Drive (Optional):

    Western Digital Blue 1TB (Opt.)

    This drive can be used instead of or in addition to the solid-state drive recommended earlier in this guide. If you need the capacity offered by a hard drive, then there really is no substitute in terms of value per dollar. We therefore recommend hard drives for bulk media and data storage needs, and this model offers above-average performance and quiet operation. Note that you'll need to buy an extra SATA cable if you'll be using this plus an SSD and DVD burner.

    The Guru's Tip:

    Using an SSD for the operating system and main applications, along with a hard drive for data, provides an incredibly-responsive user experience along with plenty of storage capacity. Read our SSD Setup Guide to learn how to make sure they're running optimally.

    Video Card (Optional):

    Zotac GeForce GTX 1050 Ti 4GB (Opt.)

    Due to newfound competition in the mid-range video card market, there's plenty of choice for gamers on a budget. Right now, the GTX 1050 Ti 4GB is the clear value leader in the under-$150 arena, providing excellent performance with unmatched efficiency. That what it allows it to be so compact and run without an any additional power connectors installed.

    The Guru's Tip:

    Note that many video card models will be too large to fit in this system. We've purposefully selected a smaller model to make sure there are no clearance issues.
