Tecnoware Power Systems - Silent 550 ATX Power Supply 550W Pure Power 12cm Silent Fan 2 x SATA 1 x 24 Pin Over Voltage Protection CE & Rohs Certified, 550

Great buy to replace ancient PSU in ancient office desktop. Power, CPU and SATA power cables all fit and PSU itself, being only 8cm deep fits in ancient ATX case with no issues at all. Bargain of the day.

and very well and very silent

Don't be fooled! Short leads meaning no use in a full atx system, no powerlead given, only 360w on 12v rail, not suitable for use

CONS: The advertised wattage is a bit misleading, my 550w unit has only 346w on the 12v rail where it matters the most. Fortunately, because these PSUs come with no PCIe connectors for graphics cards, there are very few situations where you're likely to draw enough wattage for that to be a problem. Lightweight and cheap, very few connectors. No power cable, but can't complain for this price. PROS: Inexpensive. No ketchup and mustard! Has flat black cables, and for once, the fact that this has so few connectors is a bonus for me because I'm using it in an ITX case where space is at a premium. The GPU I used, GTX 1650, does not require a PCIe cable, and full system draw is only about 200w at most. This is about the most I would trust this PSU with, a 65w i7 and a 75w GPU. Anything else is pushing it. Overall, okay for the money, fan seems nice and quiet and cable length is quite good for such a cheap unit. I can never recommend a cheap PSU to anybody for any reason, but I'm a hypocrite and just needed something for a low powered mini HTPC build. In my case it's perfectly fine.

It will do the job but just so everybody knows, there is no floppy disk power connector on the 550watt although the specs & images do show one. Neither is it as quiet as I’d expected, and it’s very lightweight too - though the paucity of connectors does hint at it not exactly being of great ability. Not that I expected much at this sort of price although since it was only intended to replace a failed psu on a 20+ year old piece of nostalgia it will serve the purpose, but having to buy adapters for what is supposedly already included really is not good enough. And let’s face it, the hassle of returning and then sourcing a better replacement is likely to be a thankless task that would take more time and expense than it’s worth. In summary then it isn’t great but hopefully it will do the job, though probably not for the 20 plus years the previous one lasted.

Ok for a basic build if you are using the CPU's on board graphics or a card that just uses the PCI-e slot as there are no graphic card power outputs.

Does not work, will not power on. Tried several options and nothing will get this PSU to do anything. **PLEASE NOTE this is a quote from Technoware's support team** 'Just to let you know, we do not provide any kind of warranty outside EU. It is valid only for EU citizens.'

The PSU is suitable for small cases. I bought this along with a mid sized tower case and with the PSU in the bottom of the case the 24pin and 8 pin power cables will not reach the motherboard. If you have a small case or a tower that mounts the PSU at the top; likely this will be fine for cable length. Rather than return the PSU I bought wire extensions.

Funkar perfekt.

Alimentatore economico, piu silenzioso di altri anche di fascia alta. Senza pretese ma fa il suo lavoro molto bene.

merci super

terug gestuurd, niets mis met dit toestel maar de oorzaak van mijn probleem lag blijkbaar elders.

Habe bereits im März/22 mir 2 von den 550W Netzteilen gekauft und war auch erst recht skeptisch, wegen verschiedener schlechter Bewertungen hier. Die ersten 2 PC laufen nun seit über Jahr rund 6-8 Std. täglich und keinerlei Ausfälle zu verzeichnen. Verbaut sind jeweils APU mit ner 65W TDP, 2,5" 256 GB SSD, 1x 3,5" 1TB HDD, 1 CD/DVD RW Brenner und 3x120mm PWM Lüfter Habe auch weiteren die Netzteilen empfohlen und auch die laufen leise und ohne Probleme. Fazit: Für Business/Office PC's mehr als ausreichend / auch unter Last unterm Schreibtisch kaum hörbar / klare Kaufempfehlung. wer natürlich versucht sich so ein Netzteil in eine GamingPC mit dedizierter Grafikkarte - die am bessten noch 2x 6-pol Anschlüsse braucht (die das Netzteil laut Beschreibung auch nicht hat) zu verbauen, dazu noch mit x Festplatten und RGB Gehäuselüftern, muss sich nicht wundern, das es unter Last dann abschaltet. zu solchen Leuten - rtfm - oder fragt vor dem Kauf einen der sich damit auskennt.
