STGAubron Gaming PC Desktop (Xeon E5 / RX 590 8G): problems, parts and running costs

Checked: 2026-10-19

Summary

The recurring problems are paperwork and support, not measured hardware failures: the manufacturer’s own warranty terms conflict, and customer feedback for other STGAubron models describes a missing warranty in the box and unreachable support. The hardware is an aging 2012-era Xeon E5 and DDR3 platform with an RX 590 that still handles 1080p but is thirsty and fading for newer games. Recurring cost is electricity only; there are no subscriptions or consumables, and a yearly dollar figure is not supported by the inputs. It is a reasonable buy at or below $550-600 and hard to justify above $650.

Common problems and fixes

Conflicting warranty terms — one section of the manufacturer’s site advertises a “comprehensive 3-year warranty” while its FAQ and product descriptions state a one-year warranty; the affiliate site says one year of parts and labor, and the other branded FAQ gives no duration [1][3][4]. The exact terms for this configuration could not be verified. No fix; resolve the term with the seller before buying.
No manufacturer warranty in the box — a Best Buy Q&A page has a customer reporting they did not receive a manufacturer warranty with their STGAubron purchase [18]; that feedback covers a different model, but it flags a documentation risk across the brand.
Aging CPU platform — the Xeon E5 is a server processor on a 2012-era platform with DDR3 memory; Newegg’s own STGAubron Xeon E5 listing references the E5-2640, which scores 599 single-core and 2,985 multi-core in Geekbench 6, against about 1,900 and 10,500 for a modern Core i5-12400 [2][9][10]. Games that lean on one or two cores feel the gap; there is no CPU upgrade path worth paying for on this platform [1].
GPU aging for new AAA titles — the RX 590 (released 2018) handles 1080p at medium-to-high settings in most titles but struggles with newer AAA games at high settings [7][8][16]. A future GPU upgrade is the likely path [8].
High power draw — the E5-2640 and E5-2640 v2 each carry a 95 W TDP and the RX 590 a 175-225 W TDP; Tom’s Hardware measured 238 W during gaming [7][8][10][11]. No fix; this is the running-cost consequence of the platform.

Parts and consumables

No consumables are reported for this desktop. The components the inputs name have no prices:

32 GB DDR3 RAM — the platform’s memory; DDR3 is obsolete and the inputs say there is no memory upgrade path worth paying for [1][2].

The manufacturer says standard motherboards, power supplies and ATX cases keep future upgrades straightforward, and recommends cleaning dust with compressed air every 3-6 months and checking liquid-cooled systems for coolant leakage [1].

Yearly running cost

A yearly dollar figure is Not enough data: the inputs give no electricity price or usage pattern. What they support is direction: this is an older, thirstier platform than modern equivalents — 95 W CPU TDP, 175-225 W GPU TDP, 238 W measured during gaming [8][10][11]. Electricity is the only recurring cost named; there are no subscriptions or consumables.

When it is a good buy

This exact configuration (Xeon E5 / RX 590 8G / 32 GB DDR3 / 1 TB SSD) is sold only through Amazon in the US; the manufacturer’s own current catalog and Newegg do not list it [1][2].

Newegg comparable STGAubron models: Core i7 8th Gen / RX 590 / 16 GB / 512 GB at $514.41; Ryzen 3 3200G / RX 590 / 16 GB / 512 GB at $519.99; Core i7 / RX 580 / 16 GB / 512 GB at $419.99; Ryzen 5 PRO 2600 / RTX 2060 / 16 GB / 512 GB at $609.99 [2].

This configuration doubles the RAM to 32 GB and the storage to 1 TB, which the inputs estimate adds $50-100 over the base RX 590 setup. At or below $550-600 the extra memory and storage make reasonable sense for 1080p gaming and multitasking; above $650 the aging Xeon E5 and DDR3 are harder to justify [2].

Alternatives from the inputs: newer DDR4 builds are the better choice once this configuration passes about $650 — for example STGAubron’s own Ryzen 5 PRO 2600 / RTX 2060 / 16 GB / 512 GB at $609.99, and the Core i7 8th Gen / RTX 3070 / 16 GB / 1 TB at $858.99 [2].
