Should I swap my standard PSU for a custom one for an older PC?
Should I swap my standard PSU for a custom one for an older PC?
I was thinking about purchasing an xfx rx 580, but after checking my setup I'm doubtful. It's a standard cvs p4-700 from Facebook marketplace, originally bought for around PHP500 in the Philippines. I'm wondering if it could still function or if it's better to get a new one that works more reliably.
When your power supply is rated for 700W, it works perfectly with the RX580. You can also run the RX580 with a 500W PSU, as long as you're not pushing it beyond its limits.
It's worth noting that being labeled "80 plus" doesn't necessarily indicate a high standard of quality. It's important to examine the build quality of the device, review customer feedback, and carefully verify the listed voltages on the label to ensure they accurately reflect the power output. The "80 Plus White" designation isn't officially recognized by the certification bodies.
Additionally, even devices that meet these criteria aren't always reliable just because they pass the test. You shouldn't feel pressured to immediately purchase the most costly option; instead, consider factors like warranty duration and brand reputation. While a cheaper power supply might suit some setups, it could potentially harm other parts. Ultimately, making cost-saving decisions in one area might lead to higher expenses elsewhere.
punkncat is correct, the power supply quality is crucial. If you're not very experienced with it, opting for a reputable brand is advisable.
Yes, the PSU being discussed is a fake 700W model made with low-quality components, designed only for older office PCs before Pentium 4 processors. For better performance, you should opt for a quality midrange PSU or something more advanced like an RX 580. It will be significantly more expensive than this inferior option, which unfortunately comes at a high price. To give an example, such a PSU is available on Shopee for around ₱595 or about $10 USD. On Shopee, you won’t find good midrange PSUs until the ₱5000-₱6000 range.
Here are the rest of your concerns.
The PSU appears to be a low-cost option.
Avoid purchasing it.
Such an inexpensive power supply is likely built with inferior parts. It might lack essential safety and overload safeguards.
The main risk lies in failure under stress, which could damage connected devices.
It will only provide the advertised voltage at room temperature, not at the higher temperatures typical inside a case.
Power output on the 3 and 5V rails is intended, but not on the 12V rails where components like CPUs and graphics cards require more.
The actual power delivered might vary, leading to instability and troublesome issues that are difficult to pinpoint.
The cooling fan will spin faster to manage heat, resulting in increased noise.
A budget PSU can turn out to be much more costly than expected.
Refrain from buying it.
To assess PSU quality, check the warranty period.
A PSU with a 7-year warranty generally indicates reliability.
Avoid anything with less than a 5-year warranty.
