Most standard computers can take any standard Power Supply Unit with standard connectors. This means it is fairly easy to replace a PSU using an other model number, providing the size or the screw holes match.
Note that our replacement Power Supply Units are not direct replacements. The brand, model number, electric specifications and connectors may vary slightly from your original PSU and we cannot guarantee that they are 100% compatible with your hardware specifications. They are only high quality alternative PSUs and they do the job with no problem in most cases.
In rare cases you may encounter some issues and some slight adjustment may be required to fit your computer (additional connector adaptors, etc...).
Should you have any query, please do not hesitate to send us pictures of your PSU, PSU label, connectors, rear of chassis, inside of PC, together with your original PSU and PC model numbers. We usually provide a simple solution for most issues described bellow. Email us here.
Should you still need to return your item please request an RMA Number and use this Return form.
Please see a list of the questions you might have about a PSU purchased from us.
1 The PSU connectors are wrong, too short or missing
2 The PSU wattage is wrong3 The PSU voltage is wrong
4 The PSU fan position is wrong
5 The PSU current ratings are wrong
6 The PSU is missing the monitor outlet
7 The PSU model number is correct but the specifications are wrong
8 The PSU size is wrong
9 The PSU does not fit
10 The PSU does not work at all or works intermittently
1 The PSU connectors are wrong, too short or missing. Main ATX connector:-Older boards require a 20pin ATX connector and new boards require a 24pin connector, so most PSUs have a 20+4pin to fit all boards. Check if the new PSU has this additional 4pin square connector (with yellow, orange, red and black wires) often labelled “24”. It needs to be attached to the side of the 20pin connector and there is only one way to plug it in. Not to be mistaken for the square 4pin P4 connector with yellow and black wires. This similar looking connector has a different shape and will not fit near the 20pin connector anyway.Some PSUs have a 24pin or a 20pin connector only and may require an adaptor (20 to 24pin or 24 to 20pin). Please ask for a suitable adaptor if required.Note that It is OK to plug a 24pin PSU connector into a 20pin Motherboard socket, leaving the extra 4pin hanging on the side (providing there is no components obstructing the insertion on the connector).
When a 20pin connector is paired with an extra 4pin connector, its clip is wide and off centre.
When a 20pin connector is NOT paired with an extra 4pin connector, its clip is small and in the middle.

In the second picture, components are in the way, so a 20 to 24pin adaptor is required.
-Some odd PSUs have a special main connector (NAS boxes...). It may physically fit the motherboard but if the wire colours are different, damage may result. Please check your connector pinout and ask for availability.

8pin Connector:There are 2 types of similar looking 8pin connectors on a PSU. Their pinout is slightly different:-8pin EPS 12Volt connector for the motherboard. Usually on high end PSU. Also available as optional adaptors (4pin-to-8pin EPS or Molex-to-8pin EPS adaptors).-8pin (or 6+2pin) PCI-Express connector, connected to the motherboard or to the PCI-E cards. Usually on high end PSU. Also available as optional adaptors (6pin-to-8pin PCI-E or Molex-to-8pin PCI-E adaptors). Note that a beveled second pin goes to the PCI-E cards and a square pin goes to the motherboard.
