Hi, I have business line DELL VOSTRO 460 with the following specification:
- CPU: i7-2600 + BOX
- MOBO: DELL 0Y2MRG H67 LGA1155
- RAM: 20GB DDR3 (2x8, 2x2)
- GPU: ASUS GTX 750ti 2GB GDDR5 with 1 fan (GTX750TI-PH-2GD5)
- PC-E: ASUS AC1200 PCE-AC55BT Wifi & Bluetooth adapter
- PC-E: DELOCK USB 3.0 x4 controller
- 1x SSD 240GB & 1x HDD 7.2k 2TB
- 1x fan
+
- PSU: COOLER MASTER RS-400-PCAP-A3

CPU, GPU & RAM without any OC.

I’ve put a very energy saving GPU (probably only RX 550 could compete), but still I’m a little bit worried about my PSU. Will it be able to handle?

400W theoretically should be fine, but this RS-400-PCAP-A3 has awful opinions and reviews, so I’m a little bit scared.

Thx 4 help.
 
Did you buy the PSU already? It's not great at all. Id consider getting something decent like this soon, to be on the safe side:

PCPartPicker part list / Price breakdown by merchant

Power Supply: SeaSonic - FOCUS Gold 450 W 80+ Gold Certified Semi-Modular ATX Power Supply ($49.99 @ Newegg)
Total: $49.99
Prices include shipping, taxes, and discounts when available

Quality and will last you years with no issues.

You can try get by with the CM, but if it's one you've had for a while, Id strongly think about upgrading.

Thx for answers, I appreciate it. You convinced me 100% that I MUST REPLACE MY PSU. No doubt. I don’t want to take a risk to damage my components.

I’ve bought this computer second handed for 266$ (and upgrade ram, gpu, wifi card, usb controller for another 163$). I know it’s not a perfect gear but I would like to use it for 4-5 years.

Especially CPU (despite being old) is tolerable, theoretically I could put a quite strong GPU without bottleneck. i7-2600 has 8193 pkt in passmark benchmark, so not bad for sandy bridge (better than iconic i5-2500k without a huge OC).

I know that I should replace besides PSU: motherboard, case and cpu cooling, but it’s probably not cost efficient (it would costs another 200-250$). I don’t want to “over-invest” my desktop. So I will replace PSU only, use this computer for a few years and buy another one.

So I’m looking for PSU only. PSU should fulfill those requirements:
1) fit in VOSTRO 460 case (every PSU will fit?);
2) compatible with other components (every PSU will fit?);
3) top notch quality, so I can sleep well;
4) quite big power reserve, co I would possibly be able to change GPU in the future without another PSU replacement.

I’m a layman, don’t know nothing about PSU and never install PSU myself. But I’d like to do it myself for savings, maybe some youtube video will help me with this :).

I’m using this online shop for buying new gear (unfortunately it doesn’t have english version): https://www.morele.net/komputery/podzespoly-komputerowe/zasilacze-61/

But I’m open to buy PSU second handed, if offer is reliable and cost-effective.

I’ve got some local second-hand offers, like:
- Corsair VS650 (150PLN ~40$)
- COOLER MASTER G550m 550W (RS-550-AMAA-B1) (150PLN ~40$)
- ANTEC 550W 80 PLUS BRONZE (165PLN ~44$)
- Corsair AX760 760W (CP-9020045-EU) (320PLN ~85$)
- Corsair HX750 750W Platinum BOX (350PLN ~93$)
- Corsair rm850x gold box 850W (390PLN ~104$)
- Corsair RM 1000x (400PLN ~106$)

My budget is 400PLN (~ 100$), but less would be nice :).
 
If you wanted headroom and quality then something like this: https://www.morele.net/zasilacz-corsair-rm550x-550w-cp-9020090-eu-779365/

I would not buy a second hand PSU. Just my own preference. So I won't advise you to do it.

I’ve decided to buy second-hand SEASONIC G-550 for ~50$.

Specification:
- 550W, 540W on +12V;
- 80+ gold;
- DC to DC;
- japanese capacitors;
- 1/2 modular;
- 4-years old;
- used with ASROCK Z87 Extreme4 + i5-4690 + GeForce 970.

Maybe it is mistake but I’ve got mental blockade and don’t want to buy PSU that is worth 1/3 of my desktop value (266$). I know that it’s risky, but whatever, what will be, it will be :).

Thx for help, I appreciate it. Topic may be closed.
 


Well, good luck so :) The Seasonic unit is an older one, but it was very decent in it's day. Hopefully it will last for you.
