Amazing power supplies for too little cash and how to connect usb strips

Hi there you all!!!!! I'm testing some overclocks in my rx 570, but in some games, the computer turns off when the oc is applied. I thinks its because of the psu. So i went online and started to look for a new psu (mine is kinda cheap and only outputs 650) and i was blown away by the amazing deals. I mean, an 800w psu for only 48 euros (https://goo.gl/pSLd3K)? Even a 900w one for only 57 euros (https://goo.gl/GERoKH). Are those psus any good? From what i've seen so far, they are great, but they seem too good to be true. What psu would you guys recommend?
Also, i want to add some rgb to the inside of my pc, but the rgb strip i found needs a usb port. Is there any cable that transforms psu cables into usb?

CPU 100W, (65W and 35W added for overclock)
GPU under torture 220W (https://www.tomshardware.com/reviews/amd-radeon-rx-570-4gb,5028-15.html) numbers from here plus 10%. my estimates are high actual usage will be less.
which still leaves 230W of 550W available for the rest of the system.
a decent quality 450W unit would do the job
a decent quality 550W would not break a sweat.

even mild overclocking with the KEEP OUT units or similar quality is not advised and COULD damage the hardware its powering

While I'm not familiar with either, and the website doesn't give much in the way of spec - at those prices, they're almost certainly junk.

The "800W" and "900W" listed on them are extremely unlikely to be remotely accurate.

Please post your full system spec.
A good quality 650W unit should have no issues whatsoever, so I assume you currently have a PSU of comparable quality to the ones you've linked.

What kind of budget do you have for a PSU? Where are you located, specifically?


No, if your RGB strip needs usb, you'll need to connect to the motherboard itself (or an external port, depending on the specifics).

Those are horrible units...You want a decent unit you need something in the tier 1 or 2 range...

Ideally you want something made by seasonic...IMHO

the wattage does not make a good power supply, garbage comes in all wattages. I have never heard of Keep Out PSU's and on that alone I suggest against getting one, the 85+ rating on the label is another, there is no 85+ certification.
https://en.wikipedia.org/wiki/80_Plus
I am assuming Spain due to the language in the links and currency rates

its more expensive, has a lower wattage but it is a quality part. 5 year warranty and 550W is enough for almost any computer.
to be sure what are your specs?
what PSU do you have now?

My budget is really low. I only have ±50 euros. I wanted to buy the most powerful psu, so i dont have to upgrade it in the future. I live in Spain, Canary Islands, Lanzarote. My system specs are as follow Ryzen 5 2600 @ 4.00 Ghz, Rx 570 sapphire pulse (8 Gb), Corsair Vengeance DDR4 8x2 @ 2750 Mhz, MSI B450M Mortar, NOX INFINITY SIGMA. Thanks ^^

currently own a 20 euro 650W psu. Here are my system specs Ryzen 5 2600 @ 4.00 Ghz, Rx 570 sapphire pulse (8 Gb), Corsair Vengeance DDR4 8x2 @ 2750 Mhz, MSI B450M Mortar
I dont think a 550W psu will do the job, as my gpu requires at least 650w and i really dont wanna change my psu every 2 years (i upgrade my pc quite often).

Ok - how is shipping to the Lanzarote? Not sure if you get hit with sizeable shippings costs from mainland Spain or even Portugal?
While I doubt you'd get any decent deals, I assume you'd have to part EU import if you were to bring in from Morocco despite the proximity?
(Love Lanzarote btw!.... and Tenerife!.... and Gran Canaria for that matter!)

Any decent 450-500W unit should be more than capable.

Unfortunately, 50EUR is going to be a little tight for a quality unit.

The best for the money I can find, is a 450W Integra M from Fractal Design - at 59EUR.

A quality 450W+ will do it*. The 20EUR "650W" unit likely never will.
Quality matters much more than the claimed wattage listed.

*Unless you're pushing some ridiculously high OCs on a 570, which they're not really capable of without exotic cooling anything.

Im actually trying to push my 570 to its limits. Im currently at 1480 Mhz, if i go any further than that, the computer turns off. Import from morocco? Is that even a thing? Theres this one website called pccomponentes thats kinda neat. They have low shipping prices to lanzarote and the added bonus that we (canarios) dont pay iva (21% tax), we pay igic (only 7% tax), rendering the products way cheaper. Im gonna call the after mentioned shop and ask for information about the psu i listed earlier.

Yes, it's a thing - it's rare (as there's limited availability), just trying to establish where your options are.

Which PSU did you list earlier? The only ones I recall you listing are complete junk and, even if you don't pay tax on them, that's pretty expensive for a paperweight! :lol:

Those were the ones i listed. Im gonna contact the sellers to ask about warranty and all that stuff. Thank you for your help, appreciate it

Warranty won't matter one bit - even if the store warrants it, they'll replace with the same junk each time.

Honestly, invest in a quality unit - even if it is 'only' 450-550W, it'll be able to do it reliably, the alternates will not
